PCAD Toolkit
PCAD Toolkit is a swimming pool cost estimator and project definition system built around tasks, breakdowns, parts, labor, vendors, calculations, and cost summaries.
Project Cost and Definition
PCAD models project scope through tasks and breakdowns, then connects materials, operations, and calculation rules to cost outputs.
The system is designed to help review pool costs by supplier, task, part, labor, phase, and project assumptions.
The application brings estimating, bill of materials thinking, vendor review, and project definitions into a single web-based workspace.
Architecture Lessons
The project exposed important data-model lessons about snapshots, vendor dependencies, duplicate data, and the cost of changing foundation rules late in a system.
PCAD remains a useful project story because it shows what happens when an ambitious estimator needs a stronger relational foundation.
It also documents why a rebuild may be more honest than continuing to extend a data model that cannot support long-term changes safely.
